I'm trying to access my Calibre library via Trook on my Nook but can't get it to work.

I go to "My Feeds" in Trook, add the url of my library on the Calibre server <http://xxx.x.x.x:8080> and get a response that the feed "Could not be fetched...connection refused."

Do I add anything else to the url? Am I supposed to be putting in credentials somewhere, since the Caliber library settings ask for username & password? I've got Calibre running on my laptop when I try it in Trook, and wifi lock is activated on my Nook.
